Thank you so much. My son says he thinks period 6 has 36 energy levels--not 6. Can you let me know about this.

Hello, thanks for your reply.

There are seven possible energy levels. The number of energy levels (n) corresponds to the row or period on which the element is located on the periodic chart. Maybe he is thinking of number of total orbitals for an energy level. The total possible number of orbitals for an energy level is n^2. So, for period six this would be 36 (theoretically, since only s, p, d, f sublevels are used for the known elements).

Hope this helps!

Thanks a lot. I left an accept and \$8 bonus. Hope I did that right and you got it. Thanks again.

Yes, I did get it and thank you very much! Glad I could help out.
